This is one of the worst books Prima has put out yet. It has good strategy sections, but when it comes to facts, this book is full of errors. The fish and insect charts are simply wrong in many cases, saying certain species aren't available in some months when they really are and vice versa. Prices of housing additions are wrong. Information about store hours is wrong. Finding info on a specific item is extremely difficult, since nothing is in alphabetical, no pictures are supplied, and the name of the items is in small print. The calendar of events is wrong, with erroneous dates and missing events etc. What's even worse, the Prima website does not have an errata posted that corrects all these problems. Go for the Nintendo Power guide. You'll be a lot happier. You can get it at Nintendo's website free with a subscription to Nintendo Power magazine.
